Grain size and amount of martensite formation affect the tensile strength of the alloy and these two factors are in turns related to the cooling rate of the welding process. There was found a trend of decreased tensile strength with the increase of welding heat input and a trend of increased tensile strength with the increase of welding cooling rate. Considering the effect of cooling rate on ductility, it was found that the higher the cooling rate, the larger is the relative elongation and hence the higher the weld's ductility.
